The hypothesis is that the substitution of multi-day oral aprepitant with (intravenous) IV fosaprepitant, in combination with a 5-HT3 receptor antagonists (5HT3RA) + dexamethasone will provide comparable protection from 5 day cisplatin chemotherapy induced nausea and vomiting, compared to the results of our prior study of aprepitant. This study will be the first clinical trial evaluating fosaprepitant in patients receiving multi-day cisplatin. This will be a single arm, phase II study. The investigators propose to utilize intravenous (IV) fosaprepitant on days 3 and 5 of the 5-day cisplatin chemotherapy regimen. It is anticipated that fosaprepitant can suppress delayed chemo-induced nausea and vomiting for 2-5 days after therapy. This study will test the value of fosaprepitant in this patient population.
